Russia's invasion of Ukraine is starting to spill into Russian territory. Shelling in the Belgorod region left at least two dead and several others injured.

That is being combined with a wave of drone attacks on Moscow and on oil refineries, other strategic locations, again, which the Ukrainian government says they're not directly responsible for, but we all know is ultimately aimed at trying to destabilize Russia. Vladimir Putin has acknowledged that recently, saying that those efforts mustn't be allowed to succeed.
